Double Side Break Switch - LD2

Double Side Break Switch – LD2

The LD2 is a simple design using only the best available materials.

High-conductivity extruded aluminum terminals, extruded aluminum blades, stainless steel pivot shaft, aluminum pivot housing.

All parts are fabricated from extruded aluminum or machined from solid billet materials, such as 304 stainless steel and hard drawn copper.

NO CASTINGS

- Main contacts are silver plated copper to silver plated copper. The copper parts are tin plated when in contact with an alu- minum surface. All tinned copper-to-aluminum interfaces are cleaned of oxidation and permanently sealed with an oxydation inhibitor. Self lubricating AgC contacts are available as an option
- Contact fingers are self-resilient and do not require any additional springs to provide contact pressure. During a short- circuit, the electrodynamic forces increase contact pressure.

The LD2 is available in W Configuration
